Abstract
The structure and reactive properties of alumina-supported molybdena, vanadia and molybdena–vanadia above monolayer coverage are studied by XPS, XRD, Raman spectroscopy and methanol temperature-programmed surface reaction (TPSR). Alumina-supported series are prepared by impregnation. Reference bulk Mo–V–Al oxide systems are prepared. The bulk Mo–V–Al oxide system provides structural references to characterize the alumina-supported series. The Raman bands of AlVMoO7 are reported here for the first time, to the best of our knowledge. It is shown that the chemistry of the bulk Al–V–Mo system is also present in the alumina-supported Mo–V oxide catalysts. Methanol TPSR data show that the systems possess essentially redox activity.
